Original  copies  in  printed  paper  covers  are  filmed 
beginning  with  the  front  cover  and  ending  on 
the  last  page  with  a  printed  or  illustrated  impres- 
sion, or  the  back  cover  when  appropriate.  All 
other  original  copies  are  filmed  beginning  on  the

sion, and  ending  on  the  last  page  with  a  printed 
or  illustrated  impression.

Maps,  plates,  charts,  etc.,  may  be  filmed  at 
different  reduction  ratios.  Those  too  large  to  be 
entirely  included  in  one  exposure  are  filmed

right  and  top  to  bottom,  as  many  frames  as 
required.  The  following  diagrams  illustrate  the 
method:

way  that  lainiaeus  umlei'stood  it  wiieii  he  wrote  the  Species  I'lantarum.  His  contem- 
poraries, however,  and  tlie  iiotanists  foi-  some  years  after  his  time,  held  ipiite  ditlercnt 
views  as  to  its  limits.  At  one  time  or  another  the  ,uenus  as  we  now  \niderstand  it  has  heeii 
divided  into  as  many  as  eiiiht  oi'  ten  genera,  .\danson.'  for  instance,  foundecl  a  genus

Linnaeus  included  the  latter  two  iiron|)s  under  Pi)!i/(/(iiniiii.  tlie  former  not  l)ein,a'  known 
in  his  time,  in  my  opinion  all  three  form  ju'i^feetly  u'ood  liciiera.  We  have  excellent 
chai'aetei's  in  the  case  of  Fdi/n/ii/rinii.  This  type  I'esemides  y'<;///7o/N///(  in  its  hahit  more 
than  the  other  two  forms  in  (|Uestion,  hut  its  tissues  have  a  characteristic  texture  and  its 
leaves  a  tlistinctive  shape.  The  most  important  ditterences,  however,  exist  in  the  Mower 
and  fruit.  The  calyx  withers,  or  remains  unchanged  in  fruit,  the  faces  of  the  achene 
are  pinnately  striate  and  the  an.ules  more  or  less  n>ariiine(l  or  crested,  and  the  eml)ryo 
is  central,  the  l)road  cotyledons  almost  dividin.ii'  the  mealy  alliumen  into  halves  iiy  an  S- 
shaperl  curve.  None  of  these  characters  ai'e  possessed  liy  I'li/i/i/otuiiit.  In  I'lih/i/diic/ld 
we  lind  a  \-eiT  strong'  character  in  the  hahit  of  the  species,  and  they  all  possess  it  in  aiiout 
the  same  decree.  Mere  a<;ain  the  Mowers  furnish  characters  to  separate  this  type  from 
]'nli/(/diiinii.  in  the  tir.st  place,  the  pedicels  are  normally  solitary,  whereas  in  l'i>/i/<ji))iiiiii 
they  are  fascicled,  and  secondly  the  calyx  either  remains  unchan,iied  or  tfe  three  inner 
seyinents  develop  into  conspicuous  win;is  in  fruit,  two  chai'acters  not  helon,i>ing'  to  I'dli/- 
i/diiiiiii.  Tlit/sdiiclld  has  uDod  characters,  hut  as  we  are  not  directly  coticei'ne(l  with  it, 
suttice  it  to  say  that  its  aMinities  are  closer  to  I'oli/i/didlln  than  to  I'D/i/i/diniiii.  and  as  the 
former  .iicn us  is  distinct from  the  latter,  if  Thi/sdidlhi  could  not  stand  .u'eiierically  distinct 
it  would  naturally  fall  into  I'olj/i/oiic/ld  and  not  into  I'dh/i/oiunii. 

I'dli/i/iiinim  pro|)er  therefori'  consists  of  herhaceous  or  shruhhy  plants,  otteii  con- 
s[iicuous  on  account  of  their  prominently  jointed  stems.  They  are  eitlu'r  terrestrial, 
amphihious  or  a(|uatic.  and  tlu'ir  veu'etative  oruans  may  he  ulal irons.  ;^laucous.  variouslv 
puhescent  or  .yiandular.  Some  species  are  annual,  others  are  perennial  i>y  means  of  larj;e 
I'oots,  creepinji-  stems  or  rootstocks.  The  roots  ai'e  varialile  in  si/.e.  sometimes  slendei'  and 
fihrous.  often  \i\v>xv.  fusiform  and  woody.  In  dry  clay  soil  the  development  is  usually 
restricti'd,  while  in  .sand  they  ofte'i  elon.tiati'  to  a  remarkahle  de.urei'.  The  suh,y;enus  Bis- 
torta  furni.shes  two  kinds  of  Meshy  rootstocks;  the  one  is  liulhdike  and  the  other  more  or 
less  elon.uated,  either  creepin.n'  or  horizontal.  Tlii'  te.xtun'  of  the  tissues  of  the  stems 
varies  from  herhaceous  to  woo<ly.  and  the  hahits  it  has  assumed  are  manifold.  Some  are 
erect  or  prostrate,  some  Moat  in  or  on  the  water,  others  clinih  hy  means  of  recurved  prick- 
les, and  still  others  are  scaiident  hy  twining'  stems.  They  may  lie  strict  oi'  Mexuous.  in

a|)pear  as  '.erete  in  some  eases,  in  otlu'rs  they  are  channe!i>d  or  ri<lg;ed,  while  in  many 
species  they  are  gradually  or  ahruptly  enlarged  towards  the  nodes,  a  character  so  prom- 
inent in  this  genus.  The  leaves  are  alternate  ami  follow  in  a  'i  or  rarely  in  a  S  spiral.

The  llowcrs  are  apetalous.  liut  tiic  calyx  is  often  highly  colored  and  its  segments 
petaloid.  it  is  always  persistent,  and  is  usnally  accrescent  aftci-  the  flowering  stage,  so 
that  it  invests  the  achciie.  ( ilands  arc  often  present  in  its  tissues.  It  !<  generally  live- 
cleft  or  Hve-|)arted.  although  we  tind  it  in  many  cases  varying  from  four  to  si.\-cleft  or 
parted.  The  segments  are  nearly  cijual  or  the  outer  oni-s  larger  and  often  develcp  keels 
or  coii-picuous  wings  which  invest  tlie  h'uit.  I'rom  three  to  inne  stamens  are  present  in 
the  flower:  five  or  eight,  however,  arc  the  prevailing  numhcrs;  they  are  variously  in- 
.scrtc(l  on  tile  hase  of  the  caly.x.  sometimes  accompanicil  liy  a  corresponding  nuinlici'  of 
nectaries.  The  filaments  range  from  filiform  to  suhulate  or  even  liottle-shape:  they 
arc  persistent  and  sometimes  altei'iiafe  with  small  scales,  and  t!ie  olilong  or  ovoid  anthers 
are  attaclie<l  to  these  liy  their  liacks.  the  sacs  of  the  lattei' o|)ening  longitudinally.  .V 
pistil  of  varialile  length  surnaanits  the  lenticular  or  tri(|Uetrous  ovaiy.  which  is  onc- 
celle(l  and  l)ears  oni'  ovule.  'I"he  two  or  tlu'ee  style-segments  have  usually  hcen  con- 
sidered as  so  many  styles  more  or  less  united  at  the  l>ase.  in  my  opinion  this  is  an 
erroneous  way  of  interpri-ting  the  morphology.  'Die  ovary  In  oiie-celled,  hears  Imt 
one  ovule,  and  finally  produces  a  typical  achene.  So  it  is  more  logical  to  consider  the 
style  as  simple  aiid  more  or  less  cleft  or  parted.  Tiie  cases  in  which  di\ision  to  the  liase 
takes  j)lace  are  comparatively  few.  We  sjiould  theri'fori'  interpret  the  state  of  the  styUi 
as  two  or  tlu'ce  cleft  or  parted,  as  the  case  may  he. 

The  ovary  develops  into  a  lenticular  oi' ti'lipietrous  achene.  if  the  stvle-segments 
are  two  the  fruit  will  l)e  lenticular;  if  three,  triiiuctrous.  1  have  found  a  state  approach-

The  achene  is  cither  completely  invested  hy  the  eidarged  and  persistent  calvx  or 
in  a  W'W  sjiecies  conspicuously  exserte(l.  It  has  a  cori;i<-eous  or  memiiraiious  peri-

sharp  or  roundetl,  and  its  faces  concave  or  convex.  .\  single  sec(l  is  <leveloped  in  each 
achene.  This  latter  is  principally  made  uj)  of  horny  or  mealy  aliinnien,  and  usuallv 
takes  the  same  shape  as  the  pericarp,  'i'he  emhiyo  is  situated  in  an  angle  of  the  idlm- 
nien.  The  cotyledons  arc  slender,  foliaccous.  accundnait  or  incumhcnt.  The  latter  two 
characters  of  the  embryo  vary  among  the  diflerent  subgenera,  hut  they  are  constant

THE   GENERAL    ANATOMY. 

The  stems  under  considei'ation  are  composed  of  three  cylinders  which  are  derived 
from  the  three  cell-layers  of  the  endtryonic  or  mcristematic  sta.ii'e.  The  lirst,  that  arising;' 
from  {\\v  <li  riiiiiliiiii  II  lui/ir.  is  the  epidermis:  the  second,  that  followin.ii' the  epidernns  and 
derived  from  {\h-  jn  rihli  m  liti/ir.  we  will  desiiinatc  as  the  perihlematic  cylinder,  while  the 
third  and  lar,i:cst,  which  is  produced  hy  the /</(, ■)///(■,  forms  the  pleromatic  cylinder. 

These  cylinders,  in  their  mature  state,  arc  weli  dovulo[)ed  in  all  cases,  clearly  markecl 
oil' from  each  other,  and  arc  also  respectively  composed  of  the  same  tissues  ami  elements.

irowi'Vcr,  tlu' cvliiKlcrs  and   llicir  I'lciucnts  vary  in  the  (Ic.urci'  of  (Icvclopniciit.  and   tins 
latter  in  tlu'ii' general  and  particular  arraniicnicnl. 

Taking  u|)  their  slructuri-  and  relation  to  eaeii  otiier,  ami  lieyinning  at  the  peri- 
phery, we  have: 

1.  TnK  ki'I1)|:i;mis.  A  entiele.  whose  thickness  dejieiids  on  the  au'e  and  eiiviron- 
iiient  of  the  inilividual.  e(i\-ers  the  exposed  surlaee  of  the  epidermal  e<'lis  in  all  eases. 
'I'lie  epidermis  is  either  simple  or  douMe:  in  the  latter  e;ise  thei'e  are  two  layei's  ol'  (piitc 
similar  cells.  A  slight  modilication  occurs  in  section  Avicidaria.  wiiich  will  he  men- 
tioned undei'  that  head. 

Asa  I'ule.  the  two  usual  inoditicatioiis  of  e]>idermal  cells  are  present.  These  ai'e 
stomata  and  liichomes.  The  t'oi'iner  were  not  plentil'ul  in  any  of  the  examples  sludieil, 
hut  a  greater  or  less  numiier  are  devehiped  on  the  younger  pails.  .\s  regards  the  latter, 
we  lind  lidth  non-glandular  and  glandidar  trichonies:  the  former.  howcNcr.  pivddininate, 
and  as  with  the  stomata.  tlu'  ti'ichomes  are  characteristic  of  the  Vdunger  parts  uf  tiu* 
epidei'mis.  although  in  a  few  eases  they  do  e.xist  e\en  mi  the  oldesl  portions.  In  .-onie 
cases  the  iion-glandidar  trichonies  appear  as  conical  unicelhilar  hairs,  sometimes  de- 
pressed, someliiues  elongated.  luU  always  with  a  l>liint  ape.\.  Then  there  are  long 
hristle-like  hairs,  also  of  one  cell,  hut  with  a  long  attenuated  ape.x.  In  otlu'r  cases  we 
find  trichonies  similar  to  the  last  in  all  respects  save  their  heiiig  multicellul.ar.  .\s  a 
linal  modilication,  in  two  >cctioiis  we  hnd  simjile  i<v  hraiiclied  hairs.  'I'liev  aiv  multi- 
cellular, and  fork  either  at  the  hase  or  aiiove  it  into  two  or  several  prongs. 

The  glaiidular  trichonies  consist  of  lilack  or  yellow  glands  situated  at  the  ends  of 
unicellular  hairs. 

The  epidermis  is  the  lirst  element  of  the  cellular  (issues.  To  anticipate  a  little,  it 
may  he  well  to  mention  regions  of  these  tissues  as  well  as  the  rem.iiuing  elements.  I'.e- 
sid.'s  the  epidermis.  <'elhilar  tissue  is  i-epreseiiled  in  the  primary  eorte.x  hy  the  (■leiiieiits 
of  the  hypoderma.  the  large  |)aiviicliymatoiis  cells  of  the  starch-ring,  the  accompanving 
tissue  of  the  sieve-tuhes.  and  liually  the  most  typical  and  ahiindant  <leveIopincnt  takes 
|>lace  as  pith.  'I'he  other  elements  and  tissues  alw.'iys  present  are  as  follows:  \<'xt  to  the 
■'■\-i  !i-ring  there  is  a  greater  or  less  <|evelopment  orsclerenchymatous  cells  which  in  most. 
■MM'S  thrill  a  stereoiue  cylinder:  mniierous  sieve-tuhes  exist  in  the  i.liloein  regions.  aii<l 
within  lliese  is  tlie  xylein,  made  up  of  its  ditSerent  kinds  of  tracheae,  woody  pareiichvma 
and  intermediate  tissue,  all  eomhiiied  int  .  typical  collateral  hundles. 

2.  Tmk  i>i:i;ii'I.i:mati(  cvMNnKi;.  This  zone  of  the  stem  contains  at  least  two  main 
tissues  in  every  instance,  and  in  two  cases  a  tliinl  one  a;>p'  ,irs.  Foll.^wing  the  epidermis 
IS  the  primary  cortex  consisting  of  a  hypoderma  of  one  or  more  rows  of  cells  which  passes

ol>long  or  parallclopipt'dal  cflls  lyin.u  in  one  or  several  rows.  The  starch-riufi'  lies 
n.Liainst  the  third  cylinder  and  is  licnerally  continuous,  lieinji  interrupteil  in  some  cases, 
however,  hy  the  meeting'  of  the  hypodei'nia  and  sten'onie.  'I'he  perihleniatie  cylinder 
un(^'rt;oes  no  secondary  (hllerentiation,  hut  remains  in  its  primary  condition  throujihout, 
i'xci'pt  in  suhgenera  Avicularia  and  Duravia,  where  fiiscicU's  of  stereid  cells  occur;  in 
the  former  they  lie  next  to  tlu'  epidermis,  while  in  the  latter  their  position  is  near 
the  starch-ring. 

Till':  I'l.KiioMATic  (Vi.iNDKi!.  iu  this  foui'  mail!  elements  are  re[)resente(l,  namely, 
the  slereonie,  the  phloem,  the  xylem  and  tlie  pith.  Next  to  tlie  starch-ring  conies 
either  a  strong  sheatii  or  fa>cicle<  of  stereid  cells.  Tiiis  tissue  in  the  majority  of  cases 
forms  a  stereome  cylinder.  Sometimes  tlie  walls  of  these  cells  are  so  thick  that  they 
almost  obliterate  the  cavities,  while  in  other  cases  they  are  com[)aratively  thin,  in  case 
no  cylinder  is  i'ound  tliis  tissue  is  represented  hy  fascicles  at  the  outer  side  of  and  radi- 
ally with  the  collateral  huiidles. 

'I'he  phloem  occurs  mostly  as  fascicles  l>etween  the  stereome  cylinder  and  the  xylem, 
aj)pearing  in  ei'oss-section  as  areas  ranging  from  olilong  to  almost  linear,  usually  widi'ly 
separated  but  rarely  nearly  continuous  l)ut  only  slightly  disconnected  Ijetwei'ii  the  liun- 
dles  hy  the  sclerotic  or  starch-ring  elements. 

The  xylem  is  developed  accordini:'  to  the  age  and  character  of  the  individual.  Ft  is 
comjwsed  of  tracheae,  wood-parenchyma  and  intermediate  ti.ssue,  tlit.'  two  latter  heing 
most  plentiful  around  the  larger  elements  and  at  the  inner  ends  of  the  hundles,  where 
they  [lass  into  the  pith  and  in  many  easts  apjiear  as  much  like  cellular  tissue  as  tloe.s 
the  i)itli. 

The  pith  is  made  up  of  typical  [yareiichymatous  cells,  which  are  polyhedral  and 
eitlu'r  isodiametric  or  more  or  less  elongated,  with  the  exception  of  one  or  two  instances 
in  sections  Persicaria  and  Tovara,  in  which  the  cells  are  hroader  than  high.
